Equilibria — practice question

Diethylzinc, $(\text{C}_2\text{H}_5)_2\text{Zn}$, is introduced into $\text{NaOH}(aq)$. Two reactions take place. reaction 1 $(\text{C}_2\text{H}_5)_2\text{Zn} + \text{H}_2\text{O} \rightarrow \text{ZnO} + 2\text{C}_2\text{H}_6$ reaction 2 $\text{H}_2\text{O} + \text{ZnO} + 2\text{OH}^- \rightarrow \text{Zn(OH)}_4^{2-}$ For these reactions, which compounds function as Brønsted-Lowry acids?

  • A$(\text{C}_2\text{H}_5)_2\text{Zn}$; $\text{H}_2\text{O}$
  • B$\text{H}_2\text{O}$; $\text{H}_2\text{O}$
  • C$\text{H}_2\text{O}$; $\text{ZnO}$
  • Dthe reaction is not acid / base; $\text{ZnO}$
